Abstract
A support arm for use in a pen plotter having a platen with a platen extension in front of it spaced to provide a slot therebetween to rotatably support a pinch roller above the platen to prevent the edges of plotting media inserted between the platen and the pinch roller from entering the slot. The arm is slidably supported under the platen on one end and passes through the slot to rotatably support a pinch roller above the platen on the opposite end. The arm has a bridging finger extending horizontally in the slot from a point adjacent the opposite end towards the plotting media from a side edge thereof. Preferably, the bridging finger is of a width substantially equal to the width of the slot and has a top surface at the same level as a top surface of the platen.
